Progress1

Today We started our assignment. I learnt the basics of Html, htm and webdesigning. I was able to put in a login in code on my home page of my webpage and was able to login and that linked me to the 2nd page. The secound page ( as seen below) is just a simple title and a backround.

At the moment this is on the basic layout which i have yet to plan.

How do we know which is appropriate in a particular circumstance, for example how would you greet a;

·         Casual acquaintance : Hi

·         Your best friend: Hey there :)

·         Your Grandma: Hi, Hru

·         An old friend you have not seen for a long time: I havent seen you in ages , HRU?

In some ways computer systems are the same, communication between them relies upon agreed methods. These methods are called communication protocols.

The list below has some of the protocols that we have discussed before. Give an example of where they would be used.

·         TCP/IP-

·         http-

·         simple mail transfer protocol (smtp) - sending an email to another person via the internet

·         file transfer protocol  (FTP)- sending of files to another person via the internet.

·         html-

·         xml-

    Software:

    -The QR code generator is an example of a software that was used in the procwess of the self guided smart phone tours. You needed to download the QR code reader to be able to access the software that would inable u to take a photo of the code, which would redirect you to a site that would self guide you around the school.

    -Another example of a software that was used in the process of the self guided smart phone tour was the making and production of the website. Students had to create a site using google sites where they were able to edit and upload photos for the tour.

    -The teacher also used a site that allowed him to compress all the photos.

    Hardware:

    - The camera that was used to take the photos
    - The smart phone that was used to trail the QR codes.
    - The computer that was used to create the QR codes and google site.


    Constraints

    - Pre download of the Qr scanner app.
    - The size of the photos
    - Speed of the internet on both computer and phones.
    - The direction of the QR codes

    Your role in the gorup

    - creating half the google sites
    - collecting and grouping the photos in order

    Probelms you encountered and solution you created

    -p= slow internet s= doing it in own time at home
    -p= lack of time s= doing it in you own time
